The cooperative effects between the PANI (polyaniline)/nano-NiO (nano nickel oxide) composite electrode material and redox electrolytes (potassium iodide, KI) for supercapacitor applications was firstly discussed in this article, providing a novel method to prepare nano-NiO by using β-cyelodextrin (β-CD) as the template agent. The experimental results revealed that the composite electrode proce...

This paper introduces a variability-aware methodology for the design of LC-VCOs in Nano-CMOS technologies. The complexity of the design as well as the necessity for having an environment offering the possibility for exploring design trade-offs has led to the development of design methodologies based multi-objective optimization procedures yielding the generation of Pareto-optimal surfaces. The ...

We show how nanocrystalline Co films formed by separated oblique nano-sheets display anisotropy in their resistivity, magnetization process, surface nano-morphology and optical transmission. After performing a heat treatment at 270 °C, these anisotropies decrease. This loss has been monitored measuring the resistivity as a function of temperature. The resistivity measured parallel to the direct...

The accurate processing of complex liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) data from biological samples is a major challenge for metabolomics, proteomics, and related approaches. Here, we present the pipelines systems threshold-avoiding quantification (PASTAQ) LC–MS/MS preprocessing toolset, which allows highly data-dependent acquisition datasets. PASTAQ performs co...

Address correspondence to P.W. Carr. hen preparing binary eluents containing both an organic solvent and a buffer for a buffer reversed-phase liquid chromatography (LC), one must know the solubility of the buffer in the organic cosolvent to avoid precipitation of the buffer salt. For example, one must know the highest percent organic cosolvent (that is, %B, v/v) in which a buffer salt remains s...

Chromatographic behavior of co-eluted compounds from un-extracted drug-free plasma samples was studied by LC-MS and LC-MS/MS with positive APCI. Under soft gradient, total ion chromatogram (TIC) consisted of two major peaks separated by a constant lower intensity region. Early peak (0.15-0.4 min) belongs to polar plasma compounds and consisted of smaller mass ions (m/z<250); late peak (3.6-4.6 ...

0.1016/j.nanoen.2 lsevier Ltd. All rig thor. [email protected] Abstract The reversibility and stability of Li2S electrode can be improved by carbon coating on nano sized Li2S. However, how to uniformly coat a dense layer of carbon on nano sized Li2S is still challenge so far. Here, we utilized a novel flowable ionic liquid (1-Ethyl-3-methylimidazolium dicyanamide) as a carbon precursor to uniformly...

Characterization of post-translational modifications (PTMs) therapeutic antibodies is commonly performed by bottom-up approaches, involving sample preparation and peptide analysis liquid chromatography-mass spectrometry (LC-MS). Conventional requires extensive hands-on time can increase the risk inducing artificial as many off-line steps - denaturation, disulfide-reduction, alkylation tryptic d...

An impurity of Ampicillin sodium formed during a gradient reverse phase high performance liquid chromatography (HPLC) analysis of stress stability samples of the drug substance Ampicillin sodium, and the level of this impurity was found at up to 0.9%. This impurity was identified by LC-MS and characterized by (1H NMR, LC/MS/MS, elemental analysis). Based on the spectral data, the impurity was n...
